CROSS REFERENCE TO RELATED APPLICATIONS

The present application is a continuation application of U.S. patent application Ser. No. 12/327,999, filed on Dec. 4, 2008. The disclosure of this document, including the specification, drawings, and claims, is incorporated herein by reference in its entirety.

BACKGROUND

1. Field of the Disclosure

The present disclosure relates to computer telephony systems. More particularly, the present disclosure relates to interfacing computer telephony interface drivers with applications.

2. Background Information

Recently, there has been an increased integration of computer systems with the existing telephony infrastructure. One system for accomplishing such an integration is a computer telephony interface (CTI) server. An exemplary CTI server is the I-Server from Genesys Telecommunications Laboratories, Inc.

The CTI server is capable of communicating with telephone calls to manage calls and data associated with calls. For example, an incoming telephone call, placed by a caller, may be received by an interactive voice response (IVR) application. The IVR application generally plays recorded messages to the caller and receives either responses entered by the caller on a touchtone telephone keypad or voice responses communicated by the caller that can be converted to text. A CTI driver interfaces the IVR application with the CTI server for transmitting responses received by the IVR application to the CTI server for storage and for transmitting data from the CTI server to the IVR application for distribution to the client.

A computer-readable medium 182 is a tangible article of manufacture, from which sets of instructions 184 can be read. Further, the instructions 184 may embody one or more of the methods or logic as described herein. In a particular embodiment, the instructions 184 may reside completely, or at least partially, within the main memory 120, the static memory 130, and/or within the processor 110 during execution by the computer system 100. The main memory 120 and the processor 110 also may include computer-readable media.

In an alternative embodiment, dedicated hardware implementations, such as application specific integrated circuits, programmable logic arrays and other hardware devices, can be constructed to implement one or more of the methods described herein.

Further, the instructions 184 may be transmitted or received over the network 101 via the network interface device 140.

A system for providing communication systems 201 is generally shown in FIG. 2. The system 201 includes a primary CTI driver 203 configured to interface a CTI server 205 with an application 207 for transmitting client information between the application 207 and the CTI server 205. The CTI server 205 may be any computer that makes services, such as, but not limited to, access to data files, available to applications on a network in a computer telephony integration system. An exemplary CTI server 205 is the I-Server from Genesys Telecommunications Laboratories, Inc. The application 207 may be any server or program stored in a computer readable medium which interfaces with the CTI server 205 to perform a task. In an exemplary embodiment of the system 201, the application 207 is an interactive voice response application. In another embodiment of the system 201, the application 207 may be a user interface client which may allow users of the CTI server 205 to examine data that is stored in the CTI server 205. Exemplary user interface clients include enterprise access service layer applications, perifonics applications, and call setup applications. In further embodiments of the of the system 201, those skilled in the art appreciate that other applications may be used in the system 201 such as, for example, a queue.

The system 201 additionally includes a secondary CTI driver 209 configured to redundantly interface the same CTI server 205 with the same application 207 for transmitting the same client information between the same application 207 and the same CTI server 205.

In the system 201 as shown in FIG. 2, the primary and secondary CTI drivers 203, 209 may retrieve messages from the application 207 and transmit the messages to the CTI server 205. The primary and secondary CTI drivers 203, 209 may also receive responses from the CTI server 205 and transmit the responses to the application 207.

The CTI drivers 203, 209 may receive a message from the application 207 by monitoring the application 207 for a message that is directed to the CTI server 205. When such a message is located on the application 207, either the primary or secondary CTI driver 203, 209 retrieves the message from the application and sends the message to the CTI server 205. In an embodiment of the system 201, the CTI drivers 203, 209 may locate messages on the application 207 by periodically polling the application 207 to request the next message to be handled. Additionally, or alternatively, the CTI drivers 203, 209 may employ other methods of determining when messages are waiting on the application 207. For example, the CTI drivers 203, 209 may receive a broadcast from the application 207 indicating that a message is waiting, may examine a bit or flag that indicates when a messages is waiting, etc.

The CTI drivers 203, 209 may receive a response from the CTI server 205 by monitoring the CTI server 205 for a broadcast from the CTI server 205 that a response is ready. Additionally, or alternatively, the CTI drivers 203, 209 may periodically poll the CTI server 205 to determine when a response is ready. The CTI drivers 203 receive a response from the CTI server 205 and prepare a message (e.g., marshal the response) for retransmission to the application 207.

In the system 201 as shown in FIG. 2, the primary and secondary CTI drivers 203, 209 are configured to interface a single application 207 with a CTI server 205. However, in alternative embodiments, the primary and secondary CTI drivers 203, 209 may be configured to interface multiple applications 207 with the CTI server 205. For example, the primary and secondary CTI drivers 203, 209 may be associated with a single CTI server 205 and may only retrieve messages from an application 207 that is associated with that CTI server 205. Alternatively, the primary and secondary CTI drivers 203, 209 may interface multiple applications 207 with a CTI server 205, but may only retrieve messages that are associated with the CTI server 205 by checking a parameter associated with the messages. Of course, persons of ordinary skill in the art will readily appreciate that other monitoring apparatus are likewise appropriate.

In providing redundancy, a primary monitor 211 is preferably configured to monitor the primary CTI driver 203, and the secondary CTI driver 209 is configured to interface the CTI server 205 with the application 207 in response to the primary monitor 211 monitoring a failure of the primary CTI driver 203. Additionally, as shown in FIG. 2, a secondary monitor 213 may be configured to monitor the secondary CTI driver 209. In such an embodiment, the primary CTI driver 209 may be configured to interface the CTI server 205 with the application 207 in response to the secondary monitor 213 monitoring a failure of the secondary CTI driver 209. Furthermore, the primary and secondary monitors 211, 213 preferably monitor each other for detecting failures of the primary and secondary CTI drivers 203, 209. The primary and secondary monitors 211, 213 may monitor each other using any standard real-time protocols such as, but not limited to, HTTP, TCP/IP, and UDP protocols. However, HTTP is currently preferable due to its simplicity.

In an embodiment of the system 201, the primary CTI driver 203 is stored in a first server while the secondary CTI driver is stored in a second server different than the first server. In such an embodiment, either the first or the second server can be shut down for maintenance activities due to any software upgrades without impacting the performance of the system 201.

In an additional embodiment of the system 201, a plurality of secondary CTI drivers 209 may each be configured to redundantly interface the same CTI server 205 with the same application 207 to provide multiple redundancy of the primary CTI driver 203.

In another embodiment of the system 201, the application 207 transmits a message to a queue. In such an embodiment, one of the CTI drivers 203, 209 retrieves the message from the queue and sends the message to the CTI server 205. The CTI server 205 generates a response to the message, one of the CTI drivers 203, 209 retrieves the response from the CTI server 205, and the retrieving CTI driver 203, 209 sends the response to the queue. In such an embodiment, a CTI bridge takes the response from the queue and returns it to the application 207. The CTI bridge may also convert or adapt some or all of the response from the CTI server 205 into another format. Additionally, in such an embodiment, the monitors 211, 213 communicate with the CTI bridge to relay any changes in the status of the CTI drivers 203, 209 to the CTI bridge. Java based Management Beans or MBean is preferably used for this purpose.

A method of providing communication services 301 is generally shown in FIG. 3. In step S303 a primary CTI driver is configured to interface a CTI server with an application 207 for transmitting client information between the application and the CTI server. In step S305, a secondary CTI driver is configured to redundantly interface the same CTI server with the same application for transmitting the same client information between the same application 207 and the same CTI server.

In the method 301 as shown in FIG. 3, the primary CTI driver serves as the master or primary driver while the secondary CTI driver serves as the slave or secondary driver. Accordingly, in step S307, the primary CTI server is initially launched to interface the CTI server with the application.

In step S309, the primary CTI driver is monitored using a primary monitor, and in step S311, the primary monitor is monitored with a secondary monitor. If the secondary monitor monitors, on the primary monitor, a failure of the primary CTI driver at step S313, the secondary monitor launches the secondary CTI driver to interface the CTI server with the application at step S315.

After the secondary CTI driver is launched, in step S317, the secondary CTI driver is monitored with the secondary monitor, and in step S319, the secondary monitor is monitored with the primary monitor. If the primary monitor monitors, on the secondary monitor, a failure of the secondary CTI driver at step S321, the primary monitor launches the primary CTI driver to interface the CTI server with the application at step S307. If a failure of either the primary or secondary CTI driver is not detected at steps S313 and S321 respectively, the monitors continue to monitor each other for a failure of either the primary or secondary CTI driver.

FIG. 4 illustrates a program for controlling a system 401 for providing communication services wherein primary and secondary CTI drivers (not shown) interface primary and secondary applications 403, 405 with a CTI server (not shown) and wherein the program includes a CTI bridge. The CTI bridge includes a CTIDriveManager module which contains four modules: a persistent storage module 407, a web interface module 409, a launcher module 411, and a monitor module.

The persistent storage module 407 stores mapping and configuration rules. The mapping and configuration rules are preferably implemented as database tables, a set of classes for accessing and updating tables, and a Java Naming and Directory Interface configuration for accessing a database 413. The database 413 may be any type of data storage capable of storing information that may be used by the CTI server. The persistent storage module 407 also preferably has an abstract interface for other possible implementations.

Web interface module 409 defines the set of web pages (JavaServer Pages and HyperText Markup Language) that preferably presents the configuration stored in the persistent storage module 407 to an end-user and allows updating it. The web interface module 409 is accessible to the end-user via a network 425. The web interface module 409 also preferably provides access to a launcher servlet 415; in other words, the web interface module 409 provides the ability to remotely start the CTI drivers. In the case of a remote start, the output for each instance started remotely is preferably displayed on the web interface module 409 to identify a successful (or unsuccessful) start.

The launcher module 411 is the module that preferably launches the CTI drivers to interface the CTI server with the applications 403, 405. The launcher module is preferably implemented as a stand alone application and a launcher servlet 415 for remote access via the web interface module 409. The primary and secondary monitors 417, 419 start, stop, and manage the CTI drivers using the launcher module 411. The launcher module 411 preferably manages the CTI drivers with parameters read from the database 413.

The monitor module is a stand alone application that causes the primary and secondary monitors 417, 419 to periodically check if the CTI drivers are still running, or if they have failed. If one of the CTI drivers has failed, then one of the monitors 417, 419 starts the other CTI driver using the launcher module 407. The monitor module configures each monitor 417, 419 to operate in one of two states: primary monitor state and backup monitor state. One of the monitors 417, 419 preferably operates in the primary monitor state while the other monitor 417, 419 operates the backup monitor state. The monitor 417, 419 operating under the primary monitor state launches the appropriate CTI driver and also opens a communication channel with the other monitor 417, 419 operating under the backup monitor state. The monitor 417, 419 operating under the backup monitor state does not launch a CTI driver but keeps alive the communication channel with the other monitor 417, 419 which is operating under the primary monitor state. If the monitor 117, 419 operating under the backup monitor state detects a failure of the CTI driver being monitored by the other monitor 417, 419 operating under the primary monitor state, it launches the CTI driver it is monitoring and begins operating under the primary monitor state.

The monitor module also preferably causes the primary and secondary monitors 417, 419 to periodically check the primary and secondary applications 403, 405 for any failures. In the case of a failure of one of the applications 403, 405, the monitor module initiates the CTI servlet 421 to switch to the other application 403, 405. The CTI servlet 421 supports refreshing the CTI MBean 423 which in turn updates the singleton. The CTI Mbean 423 refreshes the singleton to swap to the other application 403, 405. Additionally, or alternatively, the CTI servlet 421 may employ any other method of switching to the other application 403, 405.

Accordingly, the present invention enables high availability for CTI drivers. Although most of the components of the CTI infrastructure are highly available, currently available CTI drivers do not have automatic failover and hence they impact the performance of the whole system by reducing uptime and thereby degrading customer service. Furthermore, currently available CTI drivers need manual intervention to restart the process on a different server in case of failure, which further adds to the downtime for the call center operations. During this downtime, CTI functions are lost, forcing the customer care agents to rely on manual routing processes which further degrades customer service. In contradistinction, according to the present invention, customer care agents do not lose access to CTI functions in the event of a failure of the primary CTI driver 203 as the secondary CTI driver 209 interfaces the CTI server 205 with the application 207. Accordingly, by adding high availability to the CTI driver, customer service is improved.
